The resin parts are beautifully cast with crisp details and no visible airholes. Insulating blanket detail is molded into the re-entry and service modules. The smaller parts are numbered on their pour plugs. All parts (resin, photoetched, and decals) are numbered and are called out by such on the step-by-step exploded assembly drawings. Each step also includes painting details. A Testors, Humbrol, and Revell paint chart is also included.
